From a4bf68ca50da0ce291a464aec9b03a469ab2561a Mon Sep 17 00:00:00 2001 From: Chad Versace Date: Wed, 1 Aug 2012 21:23:47 -0700 Subject: [PATCH] dri: Simplify use of driConcatConfigs If either argument to driConcatConfigs(a, b) is null or the empty list, then simply return the other argument as the resultant list. All callers were accomplishing that same behavior anyway. And each caller accopmplished it with the same pattern. So this patch moves that external pattern into the function.
